How to Change Ink Filters - How to Change an Ink Filter
Introduction
Each ink color has a filter that removes any particulate matter from the ink as it is pumped from
the ink bag toward the printheads. The ink filters are located to the right of the AC power switch
at the electronics end of the printer around the corner from the ink bags.
When to do
The ink filter for each color of ink must be replaced at least every 12 months or after 11 bags (22
liters) of ink have been consumed. If an ink filter becomes clogged, it will trap color pigment and
affect the color balance of printed images. It can also cause damage to the ink system. It is
important to change the filter before this occurs.
If the Nozzle Check print shows one color weaker than normal, this is an indication that the ink
filter for the affected color is clogged and the filter must be replaced. Also, If you notice that an
ink reservoir takes a long time to fill, check your records for when the filter for that color of ink
was last changed. Make sure that the ink tubing from that filter is not kinked.
NOTE
New ink filters will contain air that must be released. Air in the ink filter can affect the vacuum
and result in dripping ink and deteriorated image quality as a result of nozzle dropout. Bleeding
the ink filters is a strategy to avoid persistent nozzle dropout. You must bleed any trapped air out
of the ink filters to prevent an overflow of ink into the 0.2 micron ink purge filters associated with
the purge valves located on the top of the carriage. If any of the 0.2-micron purge filters shows
signs of ink contamination you will need to place a service call to have them replaced. However,
the preferred preventative maintenance method is to bleed the ink filters on a regular basis.
Before you begin
IMPORTANT! Open the sliding maintenance station door to disable the ink pumps.
Close all of the purge valves on the top of the carriage.
Required tools
Philips screwdriver (only if enclosure thumb-screws are too tight)
Lint-free cloth
IMPORTANT
A clogged ink filter can result in damage to your printer's ink system. Particulate matter buildup
in the ink can cause problems that will require a service call. Be sure to change all ink filters
every 12 months to avoid such problems.
Procedure
1.
Open the sliding maintenance station door to disable the ink pumps.
2.
Close all of the ink purge valves (they are located on the top of the carriage).
